i have a 93 cherokke sport that blew the first motor and now i have dropped another inline in it bored 30 over. i put everything back together like it came out but it gets pissed in the mid range area,when it idles it sounds great and the same for the high range but mid sucks it stutters shakes and is not throwin any codes anybody can help please!!!

 

sounds like a misfire to me... higher RPM's u wont notice so much... u would notice alittle at idle though... double check your ignition system... make sure theres no vaccum leaks also... you can do this buy spraying starting fluid around the intake and related hoses... if the jeep idles up then you found your leak... if both seem to be fine then i would lean towards the throttle body and sensors attached...
